Which of the following is a mismatched pair ?

Options

A. Species - area graph - parabola
B. Equator - increased species diversity
C. Species richness - related to explored geographical area
D. Speciation - function of time

Answer

To determine which of the following pairs is mismatched, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Species Area Graph Parabola**:
- This concept was proposed by Alexander von Humboldt, not Bolt. The Species Area relationship suggests that as the area increases, the number of species increases, but the graph typically represents a curve (not a parabola) and is often depicted as a straight line in logarithmic scale. Therefore, this option is likely mismatched.

2. **Equator Increases Species Diversity**:
- This statement is accurate. The equator has a higher biodiversity due to consistent sunlight, warm temperatures, and stable climates, which support a wide variety of species.

3. **Species Richness Related to Explored Geographical Area**:
- This statement is also correct. The more an area is explored, the more species are likely to be discovered, indicating a direct relationship between species richness and the geographical area explored.

4. **Speciation is a Function of Time**:
- This statement is true. Speciation, the formation of new and distinct species in the course of evolution, is indeed a function of time, as it requires generations for adaptations and natural selection to lead to the emergence of new species.

### Conclusion:
Based on the analysis, the mismatched pair is **Species Area Graph Parabola**.

### Final Answer:
**Species Area Graph Parabola** is the mismatched pair.
